7. Troubleshooting
- Trimmer not turning on: Ensure the trimmer is fully charged. Check the LCD display for battery level.
- Poor trimming performance: Clean the blades thoroughly to remove any hair buildup. Ensure the blades are not damaged.
- Skin irritation: Ensure the trimmer is used on clean skin. Try using an attachment comb for a slightly longer trim. Move the trimmer slowly and gently, especially on sensitive areas.
- Trimmer making unusual noise: Clean the trimmer thoroughly. If the noise persists, contact customer support.
8. User Tips
- For optimal results, always ensure your trimmer is fully charged before use.
- When trimming longer hair, consider using the longest attachment comb first, then gradually reducing the length if a closer trim is desired.
- Always stretch the skin taut when trimming sensitive areas to prevent nicks and ensure a smooth pass.
- Regularly clean your trimmer after each use to maintain hygiene and performance.
- If you own multiple Kemei models, always verify the model number (KM-1848) to ensure compatibility with accessories like charging bases and combs.
